OIL BURNER.

Application filed June 16,

The object of my invention is to'provide a simple and effective const-ruction'of oil burner particularly well adapted for use in ieating stoves and furnaces, and the invention consists in the features of novelty hereinafter described, illustrated in the accompanying drawings and particularly pointed out in the claims at the end of this specification.

Figure 1 1s a view 1n central vertical section through an oil burner embodying my ported in any suitable manner, as by ro ds B,

hat extend upward from the bottom of the stove or furnace" and fit within sockets formed in the bosses Z) dependingbenea-th the base B. i v 1 The base Bis formed with a concavo-convex combustion chamber B open at its top and having the upper surface of its base portion 6 flat, and formed, if desired, with a central raised portion Z2 At opposite sides of the combustion chamber B? are formed the air inlet ports 0*, the walls of whichare preferably cast integral with the body of the base B, and preferably the. inner portions of the wallsof these inlet ports Lt are formed with reduced portions over which fit the depending tubular inlet portionsc of the mixing chamber C. This manner of connecting the mixing chamber C with the base portion B enables the'parts to be conveniently assembled and to be readily separated when it becomes necessary to clean them. Between'the inlet portions 0 of the mining chamber G is formed a tubular outlet c that opens above the center of the combustion chamber B Beneath this outlet 0 is placed a deflecting cone D that is preferably .formcd as a separate part set loosely upon the flat base portion 5 of the combustion chamber. The deflecting cone D resting loosely within the combustion chamber, can be adjusted to the most effective position for spreading the mixed vapors issuing 1924. Serial No. 720,152.

downwardly through the outlet port o. By forming this cone as a separate part, its

upper surface can be ground or smoothly finished so as to more effectively serverto.

uniformly spread the burning gases and render the cone less liable to become foul than if its surface were left as a rough cast mg. I j

Above the mixing chamber C and preferably cast integral therewith is a vaporizer E that is formed with a shallow rectangular chamber, the edges of whichproject laterally or outwardly beyond the walls of the mixing vchamber and hence into the path of the hot flaming gases as they rise from the combustion chamber B A supply pipe F for the oil opens into the bottom of the vaporizing chamber E near one end and upon the floorof the vaporizing chamber E is formed a rib or baffle c. This rib or baths 6 extends along the floor of the vaporizing chamber E at a slight distance from the outer walls thereof, the rib or ballle e'being of such shape as to cause the oil issuing through the supply pipe F to pass lengthwise over the floor of those portions ofthe i vaporizing chamber. that project laterallyabove the combustion chamber and are hence subjected to the greatest heat. A break or open space 6 1n the'rib or bafile 6 permits any unvaporized portions of the'oil, after it has traversed the floor of the vaporizing chamber,*to pass (as indicated by the arrows 2) on to that part of the floor of the chamber E inclosed by the rib or baffle e and thence into a. pocket or depression E" from the chamber E will be ejected. This vapor pipe G is shown as provided with one or more ports 5/ formed in its walls at a oint or points approximately in line with the floor of the vaporizing chamber E. The

pipe G has threads upon its outcr lower portion which engage the threaded opening in thebottom of thepocket or depression E, hence the vapor pipe G can be adjusted to any desired position and cantbe readily removed for purposes .of replacement or' cleaning. By thus extending the vapor pipe G through the depression or pocket E. danger of the vapor pipe becom ng clogged is avoided any solid matter-within the vaporizing chamber will tendto accumulate in the" pocket E, from which it can be easily cleaned out when the vaporizing pipe G is removed. i

The upper open end of the vapor pipe Gr extends into a cap or chamber E the lower end ofiwhioh is exteriorly screw threaded justed or withdrawn, of the vaporizingv chamber E are formed with holes that'arc closed by removable screw plugs e and the removal of these screw plugs permits the ready cleaning of the chamber E.

' From the foregoing description it will be seen that when oil is admitted through the inlet pipe F to thevaporizing chamber IE, it will be caused by the rib or bafile e, to flow along those parts of the floor of the chamber E that project outwardly from the mixing chamber C and as these laterally projecting parts oi' the mixing chamber are exposed to the greatest heatfrom the combustion chams her, the vaporization of the oil will be most effectively secured. 7 From the vaporizing chamber the Oll passes through the vapor pipe G downwardly into the outlet port 0 of the mixing chamber, where it is mingled V 1 with the incoming air as it is forced downrwardly upon the upper face of the deflecting 3 V cone 0 within the combustionchamber B "Having thus described my lnvention, what I claim as new and desire to secure'by Letters Patent is 1..
